Implement filterings using orbs or maps. www,mail-abuse.com. Also you may want to switch to postfix. Seee www.postfix.org/ press links (they link to 2 of my articles which have some content on why postfix is so damn good =).

Hi to all,

My company mail server is running on a Suse 6.3 system, with sendmail 8.9.3, and until sotime ago everything was running beautifully.

What happened is that we started to receive mail messages with links to porno sites. These mail messages are always addressed to non existant users in the mail system. We have tried to configure sendmail by way of webadmin to reject mail from the source addresses but the source adress is always changing. Is there any security problem with Suse 6.3 and/or sendmail that can cause this ?

What can I do to solve this?

Thanks in advance
